The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
Neither reinforcement nor extinction need to be deliberate in order to have an effect on a subject's behavior. For example, if a child reads books because they are fun, then the parents' decision to ignore the book reading will not remove the positive reinforcement (i.e., fun) the child receives from reading books.

Operant conditioning originated with Edward Thorndike, whose law of effect theorised that behaviors arise as a result of consequences as satisfying or discomforting.

Behavior modification is a treatment approach that uses respondent and operant conditioning to change behavior. Based on methodological behaviorism, [1] overt behavior is modified with (antecedent) stimulus control and consequences, including positive and negative reinforcement contingencies to increase desirable behavior, as well as positive and negative punishment, and extinction to reduce ...
Example: A mother yells at a child when they run into the street. If the child stops running into the street, the yelling ceases. The yelling acts as positive punishment because the mother presents (adds) an unpleasant stimulus in the form of yelling. Example: A barefoot person walks onto a hot asphalt surface, creating pain, a positive punishment.
Premack gave the children two response alternatives, eating candy or playing a pinball machine, and determined which of these behaviors was more probable for each child.
